EDWARD R. BRIGGS, OF BERKELEY, CALIFORNIA.

SED AND FERTIDIZER SCATTERER.

Application filed March 31, 1524. Seriall No. 703,161.

To all 107mm tnnay concern:

Be it known that I, EDWARD R. BRIGGS, a citizen of the`United`States of America, and a resident of Berkeley, county of Alamede,y and State of California, have invented certain new and useful Improvements 'in Seed and Fertilizer Scatterers, of which the y' followingr is ,a'full and clear specification. l

A1li,

VThe object of this invention is to provide means whereby the exhaust from the motor for drivingthe vehicle may be utilized tol scatter seed or fertilizer, as more fully here-g inafter set forth.

In the drawing-f i Fig. lis aside elevation of a motor-driven vehicle 'equipped with my invention; Fig. 2 is al vertical transverse f sectional vview ofthe hopper;

Fig. 3 is a planview of a portion ofthe vehicle; L

Fig. 4 is a rear view of'the'hopper, partly in section. c

Referring to the drawingl annexed", they ynumeral 44 designates a hopper mounted direetly on thel floor of the bodyyadjacent to the rear end thereof and extending across the vehicle. Access tosaid hopper is obtained through a trap-door 45 forming part of the bottomy of the box body when closed. `The hopper 44 is preferably provided with an inclined bottom 45 and a slit-dischargeopening 4G through which the material will automatically flow when the valvedoor 47 isopened; Pivotally connected to A the bottom of the hopper is a. closed box or chamber 47 whiehis tapered tov a narrow discharge-mouth 48 that preferably lies be-.

. neath the slit-discharge-opening 46 of the hopper, and this "closed box or chamber is connected by a pipe 48' and la iexible-tube coupling 49 with the discharge-opening of the muflier 15. The inclination'of the blowbox can be varied by pulling: or pushing on the rod 50, which preferably is controlled from the cab of the truck, the different adjustments serving to throw the material a greater or less distance from the hopper.

It will be understood that the nozzle-box `47' extends the length of the distributing hopper and that its contracted exit. lies gust under and approximately .parallel with e ongated discharge-opening 46 of the hopper. For the purpose of equalizing the pressure in the nozzle-chamber 47', I provide a bathewall 4W in the chamber which extends the full length of the exit and depends from the top wall of thenozzle to near the bottom wall thereof.

y I may provide any means for pulling and pushing the rod 50; I prefer to do this by means of a pedal 51 mounted in a position convenient to the driver, and I may provide va suitable locking device such as a ratchet segn'ient y52.for holding the pedal in its adjusted positi.on.QIt. Will-'be observed that the exhaust gases ofthe .engine 'issue `from the nozzle 48. in the 'Tform of a long `thin body extending the length ofthe hop- `per, just under the dischargefopening thereof, whereby the blast will'strike the falling 'seed or fertilizer/and scatter the'same in a rearward direction. The battle-plate 49 prevents the blast driving directly to the nozzle exit and insures distribution of the lblast throughoutl the length of ,the'hoppelg Vso fthat'the blast may issue from the exit at' a substantially uniform pressure throughout ,the lengthv thereof. f ,This baille also tends to breakdown vthelpulsationys of the exhaust productsand thereby' tends to accumulate a pressure in-the chamberft 4to thereby insure 'the blast as i't Vissues from the exit being'forall practical purposes'continuous. i

' lVhat I claim as new is:

1. In a motor vehicle for gricultural purposes, a hopper having a discharge-opening, and means for utilizing the power of the exhaust from the motor ofthe vehicle to distribute the material falling from the hopper, vsaid means embodying an elongated blast vnozzle arranged underneath the hopper and adapted to direct the blast into the material falling from the hopper, said blast nozzle having a baille-plate extending longitudinally thereof and enclosed within it.

2. In a motor vehicle for agricultural purposes, a hopper having' a discharge-openingr, and means for utilizing the power of the exhaust from the motor of the vehicle to distribute the/material falling from the hopper, said means embodying an elongated blast nozzle arranged underneath the hopper and pivoted thereto, so as to permit its exit edge to be raised and lowered, and means for actuating' the blast nozzle.

In testimony whereof I Ahereunto affix my signature.
